Peter Thiel is a billionaire and one of the best-known investors in Silicon Valley.

But the PayPal cofounder says that none of his success would have happened if he had continued on his career path as a lawyer, which was, as he describes it, a "familiar track." Instead of continuing down that road, he moved out to California, cofounded a technology startup, and made a fortune.

During a commencement speech at Hamilton College on Sunday, Thiel spoke out against conventional wisdom and the familiar track, pointing out two big clichés that end up being wrong more often than they're right.

The first cliché that Thiel takes a shot at is "to thine own self be true." He said:

Now Shakespeare wrote that, but he didn't say it. He put it in the mouth of a character named Polonius, who Hamlet accurately describes as a tedious old fool, even though Polonius was senior counselor to the King of Denmark.

No evidence-based process for assessing personal genetic tests yet exists. Nevertheless, according to

One of the top Apple followers is worried that it could turn into BlackBerry

If Google is right about the future, there are troubling signs to suggest Apple could meet the same fate as BlackBerry, according to top Apple follower Marco Arment.

In a blog post, Arment argues that BlackBerry was great at creating phones and dominated the market before Apple released the iPhone.
